same on both the local and the server.Git is currently the world's most advanced distributed version control System (no one). What are the characteristics of git? Simply put: high-end atmosphere on the grade!The earliest git was developed on Linux, and for a long time git could only run on Linux and UNIX systems. Slowly, however, someone transplanted it to Windows. Now, git can work on the big platforms of Linux, Unix, Mac, and Windows.Install gitUbuntu Linux, with a Apt-get install git can dir

, here are three kinds. Spatial Index Search on the internet Spatial indexes are indexes on fields of spatial data types, and there are 4 types of spatial data in MySQL . are geometry, point, LINESTRING, POLYGON, respectively. MySQL uses the spatial keyword to extend the syntax to create spatial indexes that can be used to create regular index types. To create a column for a spatial index, you must Declare it as not NULL, and the spatial inde

applications. How does Django distinguish between URLs with duplicate names? For example, Vote s app has a detail view, and maybe another blog app has a view with the same name. How does Django know {%url%} which URL of the app the tag corresponds to?The answer is: Add a namespace to the root URLconf. Make a s/urls.py slight change in the vote file, plus app_name set the namespace: fromDjango.urlsImportPath from.ImportViewsapp_name='votes'Urlpatterns=[Path ("", views.index,name='Index'), Path (

by judging the array/string length ClassCastException can be avoided by instanceof keywords Concurrentmodificationexception can use iterators to circumvent (43) Avoid the use of random instances by multithreading, although sharing the instance is thread-safe, but can be caused by competition for the same seed performance degradation, after JDK7, you can use Threadlocalrandom to get random numbersWhen multiple threads acquire random numbers at the same time, they compete for the sam

It is also not possible to initialize arrays beyond the number of array lengths. Like what:int a[3]={1,2,3,4}; A compilation error is generated.Here by the way, a string in C + + is mentioned. For example, "Hello", the string length is 6. After HELLO the system adds a hidden ' + ':sizeof and the strlen Introduction: ( quoted from Baidu Encyc

life cycle. Divide the objects into young, old, and persistent generations, using different algorithms (one of these methods) for different life cycle objects. The current garbage collector (starting with j2se1.2) uses this algorithm.Divide by System threadSerial Collection: Serial collection uses single-threaded processing for all garbage collection work because it is easy and efficient to implement without multithreading. However, its limitations are also obvious, that is, the advantage of no
